取得html中的comment的内容

Html中的comment其实也有nodeType的，只是我们一直不用罢了。它的nodeType = 8哦。于是，就有了一个基于jQuery的插件：comments

// This jQuery plugin will gather the comments within
// the current jQuery collection, returning all the
// comments in a new jQuery collection.
//
// NOTE: Comments are wrapped in DIV tags.

jQuery.fn.comments = function( blnDeep ){
var blnDeep = (blnDeep || false);
var jComments = $( [] );

// Loop over each node to search its children for
// comment nodes and element nodes (if deep search).
this.each(
function( intI, objNode ){
var objChildNode = objNode.firstChild;
var strParentID = $( this ).attr( "id" );

// Keep looping over the top-level children
// while we have a node to examine.
while (objChildNode){

// Check to see if this node is a comment.
if (objChildNode.nodeType === 8){

// We found a comment node. Add it to
// the nodes collection wrapped in a
// DIV (as we may have HTML).
jComments = jComments.add(
"<div rel='" + strParentID + "'>" +
objChildNode.nodeValue +
"</div>"
);

} else if (
blnDeep &&
(objChildNode.nodeType === 1)
) {

// Traverse this node deeply.
jComments = jComments.add(
$( objChildNode ).comments( true )
);

}

// Move to the next sibling.
objChildNode = objChildNode.nextSibling;

}

}
);

// Return the jQuery comments collection.
return( jComments );
}

代码其实并不多，大概知道就好，本来是用phpQuery也这样写的。但发现。。。stick的时候，即使我选择了nodeType=8也取不到值。我晕啊，最后我只能用正则将注释取出来当成内容用了。

早先有人把代码扔在textarea里，用来当成数据加载，现在也有人开始无耻的利用注释了。真不厚道
